The two-dimensional KPZ equation in the entire subcritical regime
We consider the KPZ equation in space dimension 2 driven by spacetime white noise. We
showed in previous work that if the noise is mollified in space on scale ε and its strength is …

Optimal trade execution for Gaussian signals with power-law resilience
We characterize the optimal signal-adaptive liquidation strategy for an agent subject to
power-law resilience and zero temporary price impact with a Gaussian signal, which can …

Zeros of smooth stationary Gaussian processes
M Ancona, T Letendre - 2021 - projecteuclid.org
Abstract Let f: R→ R be a stationary centered Gaussian process. For any R> 0, let ν R
denote the counting measure of {x∈ R∣ f (R x)= 0}. Under suitable assumptions on the …

A probabilistic approach of ultraviolet renormalization in the boundary Sine-Gordon model
H Lacoin, R Rhodes, V Vargas - Probability Theory and Related Fields, 2023 - Springer
Abstract The Sine-Gordon model is obtained by tilting the law of a log-correlated Gaussian
field X defined on a subset of R d by the exponential of its cosine, namely exp (α∫ cos (β …

The scaling limit of the membrane model
On the integer lattice, we consider the discrete membrane model, a random interface in
which the field has Laplacian interaction. We prove that, under appropriate rescaling, the …

The multiplicative chaos of fractional Brownian fields
We consider a family of fractional Brownian fields {BH} H∈(0, 1) on R d, where H denotes
their Hurst parameter. We first define a rich class of normalizing kernels ψ and we rescale …

Liouville metric of star-scale invariant fields: tails and Weyl scaling
J Dubédat, H Falconet - Probability Theory and Related Fields, 2020 - Springer
We study the Liouville metric associated to an approximation of a log-correlated Gaussian
field with short range correlation. We show that below a parameter γ _c> 0 γ c> 0, the left …

Wavelet analysis of the Besov regularity of Lévy white noise
S Aziznejad, J Fageot - 2020 - projecteuclid.org
We characterize the local smoothness and the asymptotic growth rate of the Lévy white
noise. We do so by characterizing the weighted Besov spaces in which it is located. We …
